Measure Lumen

The advertised brightness of many automotive lightings and flashlights are unfortunately "inflated". Trust your own measurement.

Lighting Efficiency

Luminous efficacy (lumen/watt) is the best indicator of a bulb's efficiency. Higher luminous efficacy means more light with less energy consumption. ✅

Higher Watts ≠ Brighter

Higher watts does not necessarily lead to higher lumens. Using watts to compare lights can be misleading because more an efficient bulb can produce more light using less power.

Lumen measurement made easy

The portable integrating sphere tester makes it super easy to measure lumens without going through a photometric testing lab. Measure up to 13000 lumens and 130 watts at your finger tips.

Higher Watts ≠ More lumens

Luminous Efficacy is the best performance indicator of a light source, not Watts. Higher luminous efficacy ensures brighter light  using the same power.

✅ More efficient light

· H11 Headlight
· 38.2 watts
· 4095 lumens
· 107 lumens/watts (higher luminous efficacy)

❌ Less efficient light

· H11 Headlight
· 44.5 watts
· 3480 lumens
· 78.2 lumens/watts (lower luminous efficacy)

Not watts.

Higher watts doesn't necessarily equal to brighter light. The luminous efficacy value indicates a  bulb's lighting efficiency. Why not pay less for energy when you can get the same amount of light?

Luminous Efficacy

Higher luminous efficacy. 
More light, less watts

Use luminous efficacy measurement to easily identify the more efficient light bulb.

What is luminous efficacy and why it matters?

Luminous Efficacy is the best performance indicator of a light source, not Watts. A more efficient light bulb can produce more lumens than a less efficient one with higher watts.

When comparing two lights of the same watts, go for the higher luminous efficacy. Higher luminous efficacy means higher lighting efficiency, which ensures brighter light using the same amount of power.
